I just felt like I should ask a question about gravity, despite the fact that I should be able to figure it out by myself. Classical mechanics can be such a mess though so better safe than sorry. I just started GMing a campaign I hope will take place a lot in Earth orbit, including the lagrange stations and Luna. It really is a great place for all sorts of funky stuff, I can't believe I overlooked it before (it seems like Rimward or Mars is more alluring for some reason). Anyway, it is quite easy to think that a station in low enough orbit will feel some sort of gravity from Earth, so that even though it's small, there will be some sort of down. But then I realised that if you are in a stable orbit you will effectively be in constant free fall and since you and the station will be under the effect of the same acceleration you will in effect have a zero-g environment in the station. It can get really tricky understanding these things as they aren't always intuitive. Also these very low-g places can be very hard to visualise (especially for some players) so any tips on how to explain them is more than welcome.
